250 WATT HALOGEN SERVICE MANUAL
GENERAL THEORY OF OPERATION
The 250-watt halogen illuminator general operation is as follows. Please consult
Figure 1 for wiring information.
A.C. POWER DISTRIBUTION
The 250-watt halogen illuminator is based around a selectable input transformer.
Input line voltages of 115V ~ at 50/60 Hz and 230V~ at 50 Hz are applied at the
power input model via a hospital grade power cord. Over-current protection is
provided by two 3-amp fuses. A double-pole interlock switch located on the front
right side of the lamp heat shield, provides operator safety.
INTENSITY CONTROL
A rotating stainless steel disc that is placed in front of the lamp controls intensity.
The disc contains holes in varying sizes and patterns. Manual lamp intensity
control is made via a front panel mounted knob.
COOLING SYSTEM
Cooling is provided by a 53FM, 115 VAC fan. Air is drawn through the sides of
the unit, across the transformer and lamp, and exhausted through the rear
mounted exhaust louver. Caution should still be used, as there are still potentially
hazardous temperatures at the turret.
PARTS REPLACEMENT PROCEDURES
The following procedures are meant to aid the technician/engineer in replacing
defective or damaged components. These procedures are meant to be used by
qualified personnel only. Extreme caution should be used and all necessary
safety precautions taken when working on this equipment.
